SPECIFICATION forming part Of Letters Patent NO. 678,655, dated July 16,1901.

Application iiled December 8, 1900. Serial No. 39,160. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES E. GERVAIS, a citizen of the UnitedStates,and a resident of the city of New York, borough of Manhattan, in thecounty andl State of New York, have invented a new and usefulImprovement in Lamps, of which the following is a full, clear, and exactdescription.

One purpose of the invention is to provide a lamp adapted to burn oil orother infiammable fluid and to use an electric battery in connectionwith the lamp, the battery being Y so connected with the lamp that aheator resistance coil may be made to ignite a primary wick, the flame ofwhich will be instantly communicated to the illuminating-wick, and

to provide means whereby as soon as the illuminating-wick is ignited thecurrent from the battery may be broken and the ame at the primary wickautomatically extinguished. Afurther purpose of the invention is toprovide means for normally holding the zinc element of the battery outthrough the exciting fluid and to quicklybring the zinc element incoaction with the carbon elements of the battery.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth,v

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis speciication, in which similar characters of referenceindicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improved lamp. Fig. 2 is a verticalsection through the lamp, taken practically on the line 2 2 of Fig. 4,showing the extinguisher removed from the heat or resistance coil. Fig.3 is a side elevation of the upper portion of the lamp when the lamp isin operation, and Fig. 5 is a horizontal section taken practically onthe line 5 5 of Fig. 2.

A represents a receptacle adapted to contain an exciting fluid, and thesaid receptacle is provided with a neck 10, upon which neck a metalcollar 11 is screwed or otherwise secured. A disk or strip 12 of anon-conducting material is located in engagement with the inner face ofthe upper portion of the said cap 11, and a metal plug 13 is held in theupper portion of the cap in any suitable or approved manner, the upperface of the plug being in engagement with the aforesaid insulatin gmaterial 12.

Two carbons 14 are secured in any suitable or approved manner to theplug 13, and these carbons extend down into the exciting liuid containedin the receptacle A, as shown in Fig. 2. The position of the carbonsrelative to each other is illustrated in Fig.. 5. The plug 13 isprovided with an opening 15, extending through it and through the upperportion of the cap-11 and the non-conducting disk or strip 12. Onemanner of holding the plug in position is shown in Fig. 2, in which arod 16 of metal is passed through suitable registering openings in theupper portion of the cap and in the insulating material 12 and the plug13, a nut 17 being screwed upon the inner end of the rod 16 to anengagement with the under face of the plug 13. This rod 16 is providedwith an enlargement 18 at its upper end, and in this enlarged portion ofthe rod a horizontal opening 19 is made, and a binding-screw 20 ispassed through the upper part of the enlargement into the said opening,as is also shown in Fig. 2.

A head B is located upon the `cap 11, and this head B consists of ahorizontal base member b, an upper tubular member b', and a verticalconnecting member b2. At one portion of the base member b of the head Ban upwardly-extending tube 2l is located over an opening in the saidbase or lower member b, which opening is in registry with the opening15in the plug 13. The upright member b2 of the head is provided with alongitudinal bore, through which the rod 16 passes, and a chamber isformed in the upper tubular member b of the head immediately over theconnecting member b2, in which chamber the enlargement 18 of the saidrod is seated; but between the enlargement 18 of the rod 16 and thebottom of the said chamber a strip of insulating material is located, asis shown in Fig. 2.

A lever 22 is fulcrumed at the upper portion of the tubular upper memberb of the head B, and this lever carries an extinguishing-cap 22a. At thepivot-point of the lever 22 an arm 23 is secured, and this arm is conIOO nected by a link 24 with the upper portion of a rod 25, which rod isfree to movein the tube 21 and passes into the receptacle A through theopening 15 in the plug. A zinc plate 28 is secured to the lower end ofthis rod 25, and the said zinc plate is located between the carbons 14and is held out of contact with both carbons preferably by a carbon plug29, which extends through the upper portion of the zinc plate and beyondthe sides thereof, the said yplug engaging with the carbon elements 14of the battery thus formed.

Normally the zinc plate 28 is held within the upper portion of thereceptacle A at a point above the exciting fluid in said receptacle, andthe Zinc element 28 is held in this position preferably through themedium of a spring 27, which is coiled around the tube 21 and bearsagainst a knob 26 at the upper end of the battery-rod 25, and the lowerend of the spring has bearing on the bottom of the base member b of thehead B. When the battery-rod 25 is pressed downward,the spring 27 isbrought under tension and the zine element 28 is brought into theexciting iiuid of the battery and the battery will be in action. At thistime the extinguishing-cap 22a will be raised to the position shown inFig. 2; but when the battery-rod 25 is relieved from pressure and theZinc element is carried out of the exciting liuid the extinguishing-capwill be brought to the horizontal position shown in Figs. 1 and 3.

The upper tubular member of the head B is'lon'gitudinally cut from theseat in which the enlargement of the rod 16 is placed, and aclamping-pin 30 is passed through suitable openings in the upper portionof the said upper member b' of the-head B, so as to draw the separateportions of the said member together and clamp said member upon anobject which may be introduced therein.

A lamp C is used in connection with the battery which has just beendescribed. This lamp may be of any size and may be of any material. 1tis shown provided with an exteriorly -threaded neck 31, which receives athreaded collar 32, the said collar forming a portion of a block 33, andthis4 block is provided With a cylindrical extension 34, adapted toenter the bore or main chamber in the upper member ZJ of the head B. Inthis manner a slip connection is obtained between the support for thelamp and the head B, carried by the battery.

A tube 35, of non-conducting material, extends longitudinally throughthe extension` 34 to its inner end and up and out through the top of theblock 33, as is shown best in Fig. 2. A wire 36 is carried through theinsulatingtube 35 and is held in the enlargement 18 of the rod 16 by thebinding-screw 20, as is also shown in Fig. 2. The end of the Wire 36which passes out through the upper outer end of the insulating-tube 35is connected with a heat or resistance coil 37 made of platinum Wire,and this coil is likewise connected with arod crasse or tube 39, whichis secured in any approved manner in the block 33.

A tube 40 is passed through the block 33, and this tube 40 is adapted toreceive awick 41 for illuminating purposes. Adjacent to the tube 40 anopening ismade in the block just below the heat or resistance coil 37,and the upper end of a larger wick 42 is passed through this opening,the larger wick being what I term a primary wick,since when the circuitis completed this primary wick 42 is ignited and the ame from thisprimary wick will ignite the illuminating-wick 41. This ignition takesplace when the battery-rod 25 is pushed downward and the zinc element iscarried into the exciting fluid. At this time the extinguishing-cap 22iLis raised, as shown in Fig. 2; but the moment that the battery- Vrod 25is released from pressure the rod will be carried upward by the spring27, the Zinc element will be carried out of the exciting iiuid, and thecap 22L will be carried down to the position shown in Figs. 1 and 2 overthe resistance-coil and upper end of the primary Wick, thusextinguishing the llame at the upper end of the said wick. The circuitis through the rod 16, the wire 36, the resistancecoil 37, and the rod39 to the block 33, through the block to the head B, and through thehead to the battery-rod 25. y

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
